MASTER MORSE CODE BY EAR DotDash teaches you to hear Morse the way operators do: sounds first, never a lookup table. One guided session a day, five minutes, and the letters start to feel like words. WHY DOTDASH? • Audio-first — every character is learned by ear at full 20 WPM character speed; the dot-dash pattern is only ever shown as feedback • Koch method, done properly — start with E and T, add one character at a time, never move on below 90% accuracy • Farnsworth spacing that tightens as you improve — from 8 to 15 WPM effective, automatically • Spaced repetition — weak letters come back at the right moment, mastered ones fade out • Unit checkpoints — copy real 5-character code groups, the same test amateur radio classes use • Beep, your signal-lamp coach, listens and reacts as you learn ONE DAILY SESSION Warm-up reviews → one new character → mixed recognition, recall and sending drills → words you can already spell. Beginners hear their first letters in under a minute. PRACTICE YOUR WAY • Recall drill — hear a letter, tap it from everything you have learned • Sending drill — key the rhythm on a straight-key pad with instant grading • Word copy — real words, Q-codes and ham abbreviations built only from your letters • Daily mystery word — a word puzzle that gets slower with each try; share your solve speed • Decoder and reference library — look up or hear any character, prosign or Q-code STAY ON TRACK • Learning path with unit checkpoints and progress for every character • Daily streak and XP • Per-character accuracy and speed • A gentle reminder when your next session is ready PROFESSIONAL AUDIO • Clean sidetone, adjustable 400–1000 Hz • Character speed 5–40 WPM with independent Farnsworth spacing • Plays with the screen off PERFECT FOR • Amateur radio operators preparing for CW on the air • Pilots, sailors and anyone who works with beacons • Preppers, scouts and emergency-ready families • Puzzle lovers and anyone who wants a skill most people never learn PREMIUM Try free for 3 days, then subscribe yearly or weekly, or buy once and keep it forever.
